Technical field
The present invention relates to a kind of milk and/or the distributor (dispensing device) of milk foam (milk foam, milk froth) and coffee machine that comprises this distributor of being used for.
Background technology
At the known distributor that is used for milk and/or milk foam, milk mixes with steam (specifically being water vapour) usually, and may mix with air, so that make milk or the milk of milk foam and/or heating and the mixture of milk foam of heating.This distributor also often is incorporated in the coffee machine, is specially the coffee machine that generally also comprises the device that is used to produce water vapour.The coffee machine that comprises the distributor of integrating by known way that is used for milk and/or milk foam makes milk (not with coffee) or the white coffee (not adding the milk foam) that can make coffee (not adding milk) or heating or comprise the milk foam or the extraordinary coffee (speciality coffee) of milk bubble (foamed milk, foaming milk) (for example Cappuccino or by the iron Macchiato).
The distributor that is used for milk and/or milk foam that is being used in combination with coffee machine, generally produce vacuum (" Venturi effect ") by the steam jet in the nozzle (" Venturi nozzle ") of suitable shape, this makes and can draw a part of milk and with in the described part milk distributing nozzle from the reservoir (milk container) of filling milk via the pipeline between nozzle and the reservoir.Be only to make the milk (not having the milk foam) of heating, the milk of absorption can be in the chamber of corresponding distributor and the vapor mixing of injecting nozzle, thereby is heated.Subsequently, the milk-steam mixture of making like this can be assigned in the proper container via the form of an outlet with stable output jet from distributor.In order to make milk foam and/or milk bubble, can draw extra air (for example via the continuous pipeline that is used for surrounding air) with steam jet, and in chamber, mix with the milk that sucks separately.In this modification, the milk-steam-AIR MIXTURES of stable output pattern can be assigned to the proper container via outlet from chamber, and in this case, the mixture of the milk of heating and milk foam collects in the container.
So far, based on milk-steam-AIR MIXTURES, proposed the distributor that is used for milk and/or milk foam of multiple aforementioned type, these devices allow the user to make the milk and/or the milk foam of different modification.
For example, known a kind of distributor that is used to make the milk foam from EP 1 115 317 B1, in this distributor, utilization is arranged in the pipeline of supply milk and comprises the milk stream of the valve of a manual adjustable regulating shaft (regulating shaft) that is used to regulate milk-supply by the corresponding absorption of steam jet, can come preliminary election and/or the manual adjustments by regulating shaft to change by the manual adjustments of regulating shaft.In this case, regulating shaft is the adjustable body with the through hole that is used for milk.By suitably regulating regulating shaft, the user can influence and/or the amount of the milk that the restricted passage steam jet is drawn.In this distributor, draw separately and the air that mixes with milk can be not influenced especially.This distributor has the confined defective of possibility of making different types of milk and/or milk foam.Because only can change the milk amount of absorption,, thereby influence milk foam and/or the heating milk of making and the amount and the temperature of the mixture of milk foam of making at most so the user can only bubble milk with this distributor by the adjusting regulating shaft.Therefore, to relating to making based on the extraordinary coffee of coffee, milk and/or the combination of milk foam, this distributor is very inconvenient with being used in combination concerning the user of coffee machine, specifically be because before making specific extraordinary coffee, the user at first must come by experiment to determine valve regulating shaft expect corresponding best setting with the user.This generally needs several times to attempt.About this point, shortcoming is: the manual adjustments regulating shaft is generally consuming time, and can only inaccurately repeat.Therefore, the user is difficult to make the milk of different types of milk foam and/or heating and mixture and/or different types of extraordinary coffee of milk foam.
Also known a kind of distributor that is used to make the milk of milk foam and heating based on milk, steam and AIR MIXTURES from EP 1 688 074 B1, wherein, the air intlet that is used for supplying the pipeline of air selectively opens or closes, and this pipeline comprises the valve that is used to control the air supply.Can come the closed shape of movement of valve by motor, so that selectively open valve by starting motor and allow the air supply in this way, or shut off valve and stop the air supply in this way.This distributor also comprises the pipeline that is used to supply milk, and the user can not regulate (promptly cut off, connect and/or change) milk stream by this pipeline.Therefore, in this distributor, user's used vapour jet is drawn the milk of scheduled volume, and simultaneously inhaled air is mixed with the air of steam and scheduled volume (opening) if be used to control the valve of air supply or only with vapor mixing (closing) if be used to control the valve of air supply.In this distributor, by priming valve, the user only may make two kinds of different types of milk drinks: not with the heating milk (when valve cuts out) of the scheduled volume of milk foam ratio, or have the milk bubble (when valve is opened) of the scheduled volume of predetermined concentration.Therefore, this distributor is defectiveness also, and it has limited the possibility of making different types of milk and/or milk foam.Therefore, combine with coffee machine, when the extraordinary coffee made based on coffee, milk and/or the combination of milk foam, this distributor also provides freely selecting seldom for the user.

-be used for milk and/or the outlet device 28 of the foam of suckling, comprise: the emulsification chamber 29 that is connected to chamber 19, to be received in steam, milk and/or the AIR MIXTURES of making in the chamber 19, also comprise hole 30, be used for milk and/or milk foam from emulsification chamber 29 (and/or mixing arrangement 11) discharge, two outlets 30.1 that are used for milk and/or milk foam are led in hole 30 in this example, and
-valve 21, it comprises the adjustable regulating shaft 22 that the milk that is used for subtend chamber 19 and/or air supply are regulated.
First pipeline 15 can be via joint 15 ' be connected to pipe 42, so that guarantee from container 40 supply milk.
Second pipeline 16 is connected to the steam generator (not shown in Fig. 1 to Fig. 3) of coffee machine 1, so that can introduce steam to second pipeline if desired.
As shown in Figure 2, the end away from chamber 19 of the 3rd pipeline 17 is opened, and allows surrounding air to enter pipeline 17 at this end.Yet the 3rd pipeline is provided with check valve 18 form of membrane valve (for example with), so that guarantee that the one side surrounding air can pass the pore (supply of limit air) that is formed in the check valve 18 and enter the 3rd pipeline 17, thereby enter the chamber 19 of mixing arrangement 11, and the milk that prevents to be fed to mixing arrangement 11 on the other hand can be overflowed via the 3rd pipeline 17, and the aforementioned gas holes of may making dirty, thereby reduce air supply via the 3rd pipeline 17 in uncontrolled mode.
As shown in Figure 2, in this example, second pipeline 16 is via nozzle 16 ' lead to chamber 19, and this nozzle forms and makes and produce vacuum (according to Venturi effect) from pipeline 16 via the steam of nozzle 16 ' inflow chamber 19 chamber 19.Because first pipeline 15 (being used for milk) and the 3rd pipeline 17 (being used for air) also lead to outlet device 28 via chamber 19, so the steam jet via second pipeline, 16 injecting chamber 19 causes swabbing effect in first pipeline 15 and the 3rd pipeline 17, and guarantee that (not having the help of other pumps) milk can be via the 3rd pipeline 17 intake chambers 19 via first pipeline 15 and air, and can be there with vapor mixing and/or swirl, so that heating milk (if not via the 3rd pipeline 17 air supplies) or milk is spumed, and make the milk of heating and the mixture (if via the 3rd pipeline 17 air supplies) of milk foam by swirling with air.
The regulating shaft 22 of valve 21 is constructed to be installed in the cylinder on housing 11 inwalls in this case, makes regulating shaft 22 to rotate around its longitudinal axis 22.1, thereby can be by being conditioned around longitudinal axis 22.1 rotations.
As can be known from Fig. 3, first pipeline 15 and the 3rd pipeline 17 directly lead to housing 12 inside on the outer surface 22.2 of regulating shaft 22, in Fig. 3, reference number 15.1 expressions first pipeline 15 corresponding opening, and reference number 17.1 expressions the 3rd pipeline 17 corresponding opening.Therefore, regulating shaft 22 closable openings 15.1 and/or opening 17.1, thereby prevent that milk is fed to chamber 19 via first pipeline 15 and/or air is fed to chamber 19 via the 3rd pipeline 17, unless the passage (channel) that is formed in the regulating shaft 22 is forming continuous connection between first pipeline 15 and the chamber 19 and/or between the 3rd pipeline 17 and chamber 19.
For allowing to regulate the supply of milk to chamber 19 by regulating regulating shaft 22 (promptly by centering on the specific anglec of rotation of longitudinal axis 22.1 rotations), in regulating shaft, be formed with passage 22.3, this passage is opened towards the outer surface 22.2 of regulating shaft 22, and forming path (through-passage) at opening 15.1 places and between first pipeline 15 and chamber 19, the cross section of this path depends on corresponding (angle) position of regulating shaft 22.In the example according to Fig. 3, the passage 22.3 and first pipeline 15 overlap at opening 15.1 places, make the cross section maximum of the path between pipeline 15 and the chamber 19 of winning, thereby may be Peak Flow Rate by the milk-supply of passage 22.3.Along with regulating shaft 22 rotates the specific anglec of rotation around longitudinal axis 22.1, the cross section of the path between first pipeline 15 and the chamber 19 can change, and specifically reduce the amount of being scheduled to, its size depends on the shape and the layout of passage 22.3, depends on shape and the layout and the corresponding anglec of rotation of first pipeline 15.Therefore, by regulating shaft 22 is regulated between different precalculated positions, can change by the milk stream of first pipeline 15, and can connect and cut off to chamber 19.
In a similar manner, be formed with other passage (not shown in Fig. 1 to Fig. 3) in regulating shaft 22, this produces path between the 3rd pipeline 17 and chamber 19, and the cross section of this path can change according to the anglec of rotation of regulating shaft 22.Therefore, by between different precalculated positions, regulating regulating shaft 22, can change by the air stream of the 3rd pipeline 17, and selectively connect and cut off to chamber 19.
As shown in Figure 3, distributor 10 is provided with drive motors 25 (for example stepper motor), can be by control device 35 via circuit 35.3 these drive motors of starting, and by control device 35 being controlled the regulating shaft 22 that utilizes this drive motors rotary valve 21, thereby around the regulating shaft 22 of longitudinal axis 22.1 control valves 21.
Drive motors 25 has the axial arranged driving shaft 26 of longitudinal axis 22.1 of relative adjustment axle 22.Driving shaft 26 preferably joins rotation 22.1 releasedly to, so as can with the mode of simple possible from coffee go out oral 4 and/or coffee machine 1 separate mixing arrangement 11.In this example, regulating shaft 22 1 ends comprise axial hole 23, and the driving shaft 26 longitudinally direction of axis 22.1 inserts in this axial hole fully.For engaging producing between driving shaft 26 and the regulating shaft 22, mixing arrangement 11 is arranged on the driving shaft 26, makes an end of driving shaft 26 stretch into hole 23.For improving the stability that engages, regulating shaft 22 selectively is fixed to driving shaft 26 by fastener (not shown in Fig. 1 to Fig. 3).
Valve 21 is constructed to make: by rotation (adjusting) regulating shaft 22 between a plurality of precalculated positions, can change by the milk supply of first pipeline 15 and by the air of the 3rd pipeline 17 and supply with both.In this way, the amount that milk and air can be different is mixed, and the mixing ratio between milk and the air can (for example between 100% and 0%) change on a large scale in.
Each precalculated position is stored in the control device 35, and can by with automatically, fast and the mode with accuracy of corresponding expectation control device 35 is controlled, but utilize drive motors 25 to move to described position with repetitive mode.
In a modification, provide three different precalculated positions:
-in the primary importance (resting position) of regulating shaft 22, milk is closed to the supply of chamber 19, and air is opened (the path maximum between the 3rd pipeline 17 and the chamber 19) to the supply of chamber 19.
-in the second place (milk foam position) of regulating shaft 22, milk and air are opened (the path maximum between first pipeline 15 and the chamber 19, and the path maximum between the 3rd pipeline 17 and the chamber 19) to the supply of chamber 19.
-in the 3rd position (milk position) of regulating shaft 22, the supply of milk is limited (for the maximum access between first pipeline 15 and the chamber 19), and air is closed to the supply of chamber 19.
